Bush is (claims to be) a member of the united methodist church. So the place to look at how his values differ from his church's would be www.umc.org.
UMC: Water, air, soil, minerals, energy resources, plants, animal life, and space are to be valued and conserved because they are God's creation and not solely because they are useful to human beings. -

Bush:
http://www.nrdc.org/bushrecord/UMC: In continuity with past Christian teaching, we recognize tragic conflicts of life with life that may justify abortion, and in such cases we support the legal option of abortion under proper medical procedures.
http://www.umc.org/interior.asp?mid=1732Bush: Opposes all abortion
UMC: We oppose the use of late-term abortion known as dilation and extraction (partial-birth abortion) and call for the end of this practice
except when the physical life of the mother is in danger and no other medical procedure is available,
or in the case of severe fetal anomalies incompatible with life.Bush: Opposes late term abortion without an exception for terminal deformities of the fetus.
UMC: Health care is a basic human right.
Bush: Is willing to accept a huge percentage of people not having health care, because the tax cut for the rich is more important.
UMC: We believe private and public economic enterprises are responsible for the social costs of doing business, such as employment and environmental pollution, and that they should be held accountable for these costs.
http://www.umc.org/interior.asp?mid=1736Bush: Has taken away accountability for corporations.
UMC: We support measures that would reduce the concentration of wealth in the hands of a few. We further support efforts to revise tax structures and to eliminate governmental support programs that now benefit the wealthy at the expense of other persons.
http://www.umc.org/interior.asp?mid=1736Bush: Largest tax cuts for the rich, even as others are losing their jobs, and losing their health care.
UMC: We hold governments responsible for the protection of the rights of the people to free and fair elections and to the freedoms of speech, religion, assembly, communications media, and petition for redress of grievances without fear of reprisal; to the right to privacy; and to the guarantee of the rights to adequate food, clothing, shelter, education, and health care.
Bush: Has he done any of this?
UMC: The use of detention and imprisonment for the harassment and elimination of political opponents or other dissidents violates fundamental human rights.
http://www.umc.org/interior.asp?mid=1824Bush: Gitmo, unlimited detention without cause.
UMC: the mistreatment or torture of persons by governments for any purpose violates Christian teaching and must be condemned and/or opposed by Christians and churches wherever and whenever it occurs.
Bush: Got letters from the justice dept authorizing him to use torture. Apparently the justice dept. trumps God.
UMC: For the same reason, we oppose capital punishment and urge its elimination from all criminal codes.
Bush: all for capital punishment.
UMC: We also respect those who support the use of force, but only in extreme situations and only when the need is clear beyond reasonable doubt, and through appropriate international organizations.
Bush: Bypassed the UN vote for force in Iraq when it was clear they didn't support him.
UMC: We commit ourselves as a Church to the achievement of a world community that is a fellowship of persons who honestly love one another.
Bush: Has pushed the idea that anyone who doesn't support the US war in Iraq is an enemy (with us or against us).
